Closing Social Security’s funding gap by raising payroll taxes alone would require a jump from 12.4% to 17%, according to a new estimate that puts a hard number on one of the most politically fraught fixes in Washington. For a typical worker earning about $62,000 a year, that change would mean roughly $2,600 to $3,000 more in annual taxes.
The timing matters because the program’s trust fund is still projected to run out in 2032 unless Congress acts, and that would force a benefit cut of about 22%. The new estimate turns a long-running warning into something easier to measure: how much more workers and employers would have to send in every year to keep benefits whole.
Romina Boccia of the Cato Institute said the scale of the increase makes a payroll-tax-only fix unrealistic for most families. Workers and employers generally split the tax, which means the added burden would not fall on one side alone. Self-employed workers would pay the full amount themselves, making the increase even more direct for people who already cover both sides of the bill.
That burden is also larger than it sounds on paper because the payroll tax was set at just 2% when Social Security launched in 1937. Today, the maximum amount of individual income subject to the tax is $184,500, and raising or removing that cap has become one of the most visible alternatives. In July, Elizabeth Warren and Bernie Moreno called for lifting it, and a 2025 poll of more than 4,000 Americans found 65% of Democrats and 62% of Republicans supported lifting or removing the cap.
Boccia said the sticking point is not arithmetic but reality. “It’s financially impossible for most workers to bear that additional cost, so Congress will need to look at other options,” she said, adding that most of the people in question do not even have $400 set aside for an emergency. That is the friction in the debate: a payroll-tax-only fix could close the gap, but it would ask workers to absorb a hit many households cannot handle, which is why Congress is still being pulled toward some mix of higher revenue and lower future benefits.
The unanswered question is not whether Social Security needs help. It does. The question is whether Congress will choose to raise taxes on workers and employers, lift the cap on higher earners, trim future benefits, or assemble some combination of all three before the trust fund reaches zero in 2032.
